Van toepassing op:
βœ“ Windows 10
βœ“ Windows 11

AutoPlay = USB malware delivery: Attack: Malicious USB stick (dropped in parking lot, mailed to office), User: Inserts USB β†’ AutoPlay: Automatically runs autorun.inf β†’ malware executes (NO user interaction), Malware: Ransomware, credential stealer, backdoor. Reality: Stuxnet (2010) used USB AutoPlay, still common attack vector (social engineering + USB). Defense: Schakel uit AutoPlay β†’ user must manually browse USB β†’ malware NOT auto-executed.

PowerShell Modules Vereist
Primary API: Microsoft Graph API
Connection: Connect-MgGraph
Required Modules: Microsoft.Graph.DeviceManagement

Implementatie

Schakel uit AutoPlay: All drives: USB, CD/DVD, network drives, Policy: Turn off AutoPlay: Enabled (all drives), User experience: Insert USB β†’ NO automatic action β†’ user opens File Explorer manually. Exception: NONE (no legitimate business need voor AutoPlay).

Vereisten

  1. Intune subscription
  2. Windows 10/11

Implementatie

Intune Settings Catalog: AutoPlay Policies β†’ Turn off AutoPlay: Enabled (All drives). Effect: No automatic USB execution.

Compliance

CIS Windows Benchmark L1, BIO 12.02, ISO 27001 A.12.2.1, NIST SI-3.

Monitoring

Gebruik PowerShell-script autoplay-disabled.ps1 (functie Invoke-Monitoring) – Controleren.

Remediatie

Gebruik PowerShell-script autoplay-disabled.ps1 (functie Invoke-Remediation) – Herstellen.

Compliance & Frameworks

Automation

Gebruik het onderstaande PowerShell script om deze security control te monitoren en te implementeren. Het script bevat functies voor zowel monitoring (-Monitoring) als remediation (-Remediation).
